More About Celestia
Unlike most planetarium software, Celestia doesn't confine you
to the surface of the Earth. You can travel throughout the solar
system, to any of over 100,000 stars, or even beyond the
galaxy.
All movement in Celestia is seamless. The exponential zoom
feature lets you explore space across a huge range of scales,
from galaxy clusters down to spacecraft only a few meters
across. A 'point-and-goto' interface makes it simple to navigate
through the universe to the object you want to visit.
Celestia is expandable. Celestia comes with a large catalog of
stars, galaxies, planets, moons, asteroids, comets, and
spacecraft. If that's not enough, you can download dozens of
easy to install add-ons with more objects.
